Chronic kidney disease (CKD) is associated with high overall and cardiovascular mortality. Numerous studies have reported that increased heart rate is a risk factor for all-cause mortality. We investigated the link between sleep heart rate and artery stiffness in CKD patients.

In a cross-sectional study, we enrolled 100 prevalent Chinese CKD patients (55 males, aged 52.5 +/- A 16.40 years). Heart rate was measured with an automatic system. Arterial stiffness was evaluated by using a calibrated tonometer.
